TecH₂Ozone^TM Systems General Information

Agrimond carries a variety of patented TecH₂Ozone™ systems specifically constructed to handle the unique demands of different applications. Although the core of the technology does not change, the configuration and introduction techniques of the TecH₂Ozone™ systems are adjusted to best fit the specific industry function.

Understanding Ozone

Ozone is a gas made up of three oxygen atoms. It can be created naturally (by a lightning strike) or synthetically with an ozone generator. Ozone is the result of high electric current being passed through oxygen (O₂) molecules. If you introduce high levels of electricity to oxygen, it will break the molecular bond of the O₂ into two single oxygen atoms. These single oxygen atoms will then adhere to remaining O₂, creating ozone (O₃). It is the loosely bound third oxygen atom in ozone's molecular make-up that makes it such a powerful cleaning agent.

With oxidizing power 3000 times more effective than bleach, ozone is the second most powerful oxidant in existence. When ozone gas is introduced to an environment with bacteria, mold, or any other organic material, it readily donates one of the oxygen atoms in its chemical make-up to destroy that material. Ozone can also destroy some inorganic materials like calcium and arsenic and a number of trace metals, such as iron. Once the third oxygen atom is donated to oxidize the organic component, there is only an oxygen (O₂) molecule left. This is one reason ozone is a preferred oxidant as opposed to various chemicals, because it does not leave any type of chemical residue on materials, only pure oxygen. As a result of this, ozone gas is used in numerous applications, such as wastewater treatment, air sanitation, aquaculture, water purification, and commercial laundry.

How is Ozone Created?

An ozone generator is utilized to create ozone by using either ambient air (the air that we breathe) or an oxygen concentrator (usually found within the generator) and a series of plates that produce high electric charges. By using an oxygen concentrator instead of ambient air, the generator can produce higher concentrations of ozone with lower quantities of electrical currents, resulting in the reduction in the size of the generator needed for a particular application, lowering equipment costs. The generator takes the ambient air or oxygen and passes it across a series of plates with high electric current. Ozone molecules are formed through the separation and recombination of oxygen atoms, and the ozone gas is discharged through an exit port.

How Do You Measure Ozone?

The concentration of ozone in water is usually measured one of two ways: with an ORP (Oxidation Reduction Potential) meter or a direct-read measurement that is measured in ppm (parts per million). ORP utilizes a scale of measuring the free available electrons (which would produce a negative number), or a deficit of electrons (which would produce a positive number). This translates to a reading of oxidants in the water that may not be specific to ozone gas alone (i.e. chlorine, iodine, bromine, etc.) The main disadvantage to using ORP is the customer has no way to tell if the reading is truly the levels of ozone in water or if it is a combination of multiple oxidants in the water. Because the system cannot give an exact reading, it is difficult to know how much ozone is actually being delivered to the washers. The direct-read method measures the actual dissolved concentration of a gas, in this case ozone, in solution. This means that when a direct-read device shows 1.0 ppm (equal to 1.0 mg/L) concentration of ozone in the water, the customer knows with certainty that there is 1.0 ppm of ozone in the water.
